Kurikong Mangga or Cecid Fly, Huge Crop Losses

I wrote this last March 04, 2015:

Two weeks ago, we were hopeful that we can finally harvest mangos in the farm, after about 3 or 4 years of zero harvest due to massive attacks by "kurikong mangga" or cecid fly.  See here, some of the  young mangos in the farm, photo taken last February 14 or just two weeks ago.


I went back to the farm last weekend, our caretaker told me that many young fruits have been infected already, many have fallen to the ground already.

See the dark and black spots. The damage penetrates inside, under the skin. Horrible pests.


The other side of these three young fruits. The pests are too small, they seem to be not visible to the naked eye.

Every year, a different group of mango sprayers come to the farm. Sharing of harvest, assuming there is one, is 70 percent to the sprayer and 30 percent to the farm owner/s. This year's sprayer is supposed to have discovered new treatment or pesticides vs kurikong mangga. It showed  initially because the fruits have reached more 1 to 1 1/2 inch in height already.

But it seems the pests were simply decimated partially. Those that were able to escape and survive came back, with a vengeance.

These packages of pesticides I found in the farm. The sprayers have left them there. I took some photos last February 14. I am not familiar how effective these chemicals are.


Labels at the back.


While we will experience another loss this year in  the form of zero share, zero harvest, bigger loss is to be borne by the sprayers. I expect that their loss should be near six digits, cost of chemicals + labor + food + transportation. Their workers/sprayers go to the farm every five days on average.

Among the travails and uncertainties of agri-business.

Last Saturday, March 14, I visited the farm again. Damage to the fruits has been rather extensive. Instead  of  several  hundreds kaing  of  mangos, we  should be lucky if we can get 10 kaing. Or zero, again, for the 4th or 5th straight year. Here are some of the fruits which have fallen to the ground, and they are about 1 1/2 months away from harvest period. They have huge or wide cracks up in the tree, or lots of black spots in the skin, before they fall  down.


Poor us. But more unlucky are the mango sprayers who spent tens of thousands of pesos in our farm alone, plus probably the same amount of money in a neighboring farm.
